It has held my netbook, laptop, external drives, papers, jump drives, etc.
I love it and keep going back to it whenever I try a new bag. (It must be because I was raised by my Mom, and with my two sisters, that I have become a bit of a messenger bag / backup junkie. They changed purses a lot and I change work bags at about the same interval. )
